I was wondering what solar panel do i need to run a nano and 2 sg90 servos? The information i've gotten is the sg90 servos operates around 550mA and stall at 750mA. i have a 11.5V 150mA solar panel. Both are Voc and Isc values. If it is not sufficient to power up the components, may i know what panel do i need to minimally run them?
